Hi Stefan,

I like GTK on my desktop too, but considering the portability between di= fferent platforms, I think Qt has far better support for windows then GTK. = Although it is possible to cross compile gtk applications on windows, there= are A LOT of bugs. I actually did it once when I tried to compile another = project of mine(Gummi LaTeX Editor) to Windows, its just ...bah. I'll d= efinitely checkout your pcb routing application. I already see that it'= s written in GTK3 :P

Also about the Geber support: It's already in my roadmap, and I th= ink it would be quite easy considering gerber's format is much simpler = than ODB++. I'll start implement it if I have time.

Best,
Wei-Ning

That is interesting. I myself, and most gEDA people, are using GTK. B= ut
I know that today many people enjoy Qt more -- the reason is not always
clear. For GTK we have something similar like QGraphicsView -- Clutter.
I have considered using one of them, but was not really convinced, I
found no great example projects. So for my experimental schematics tool
(http:/= /www.ssalewski.de/PetEd.html.en) I used plain cairo drawing. I
will investigate your program when I have some more free time --
currently I am still very busy -- one of my current open source projects is my PCB router (http://www.ssalewski.de/Router.html.en), which works
not bad so far, so I really should finish it...

Thanks for the links. I think here in Germany most fab houses still o= nly
use gerber files -- at least that was the case four years ago. Maybe it
already changed.
